？Look at the statements below and the information on transport on the opposite page.
？Which section (A, B, C, or D) does each statement 1--7 refer to？
？For each statement 1--7, mark one letter (A, B, C, or D) on your Answer Sheet.
？You will need to use some of these letters more than once.
A
What is to happen about transport？ Evidently there are huge and important changes in prospect. A decade or so from now, there will have been yet another transformation in the way in which people and their goods are moved from place to place. Old techniques are being faced with attenuation or even extinction, sometimes because better methods of traveling have come along but sometimes simply because the old methods have become intolerable.
B
The development of recent decades most obviously likely to be continued is the tendency for alternative methods of traveling to coexist, and so to offer potential travelers a choice. Within large cities, underground transport is usually an alternative to several ways of traveling on the surface. Roads, railways and airlines are in competition, and there are still people who cross the North Atlantic by sea. (Most freight goes that way, of course.)
C
Oil tankers could decisively affect the pattern of petroleum distribution from the major oilfields and at the same time encourage the pipeline, which offers the simplest and often the cheapest means of bulk transport. Then, there is the Boeing 747 aircraft, which is likely to do for people what the huge tankers will do for petroleum trunk be increasingly troublesome. All these changes, promised or merely possible in the pattern of transport, have in common what is, in the broadest sense, and economic stimulus.
D
Fast transport between cities separated by a few hundred miles is becoming urgently necessary in densely populated areas. The United States Government is financing a number of exploratory investigations bearing on specific problems linking the major cities on the Atlantic seaboard. However, it remains to be seen whether the result will really beyond schemes for patching up the existing railway network to some of the more ambitious schemes which are sometimes heard of--monorails, pneumatic tubes with trains inside, and deep bored tunnels intended to enable trains to oscillate from one city to another with no expenditure of energy except for overcoming friction and air resistance.
Several means of travel will be present together, in which each can replace the others.
Samuel Butler, the great English author, predicted the view of the future world of machines in his novel Erewhon, published in 1872. Ever since, authors with less sense of satire (讽刺) than Butler have created tales of monster (怪物)machines that take over and destroy the world. In varying degrees, their imaginary monsters have the power of reproduction, which permitted them to multiply until they could capture and crush mankind.
Science today is not laughing at such extremes. Dr. J. Von Neumann, of the Institute for Advanced Studies in Princeton, very carefully considered the question: Cmn machines become highly organized enough to reproduce themselves？ His conclusion was that they may, provided they are complicated enough. Mathematically, a certain degree of complication seems to be necessary for reproduction. Below that, the iron mothers can only give birth to more primitive forms than themselves, and any "race" of robot monsters would soon lose the reproductive function.
If mathematicians are to be believed, we can rest fairly secure for a while yet. Human physiology (生理学) is still millions of times more complex than any giant brain. To copy the complexities of the human brain alone would be a shocking problem.
Transistors (晶体管) might reduce the super-giant to the size of a house and his power requirements to a few hundred kilowatts -- yet the human brain will fit into a cereal bowl and takes about twenty-five watts of power.
The author mentions Samuel Butler and other English writers' tales because______.
A．they teach logic to the readers
B．they show a sense of satire
C．they proved that machines can reproduce themselves
D．they described the imaginary future world of machines
听力原文： At present, human beings have used many devices to measure time. Perhaps, the sundial was, one of the earliest and simplest devices. A sundial can measure the movement of the sun across the sky each day.
The sundial worked very well only when the sun was shining. So other ways of measuring the passing of time were invented at that time. One device was the hourglass. It used a thin stream of falling sand to measure time.
By the 1700s, people had already developed mechanical clocks and watches. And today many of our clocks and watches are electronic.
So we have devices to mark the passing of time. But what time is it now？ Clocks in different parts of the world do not show the same time at the same time. As international communications and travel grew, it became clear we need a way to establish a common time for all parts of the world.
In 1884, an international conference divided the world into 24 time areas or zones. Each zone represents one hour. The astronomical observation in Greenwich, England, was chosen as the starting point for the time zone.
Most people have no trouble in agreeing that time moves forward. Some scientists believe there is one reason why time moves forward. It is clear we need a way to establish a common time for all parts of the world with scientific law: the second law of thermodynamics. The law says disorder increases with time.
(33)
A．It measures the length of a day and a night.
B．it measures the movement of the sun each day.
C．It measures the passing of hours, minutes and perhaps seconds.
D．It measures the shadow of the stick across the flat surface of the sundial.
SECTION 1 Compulsory Translation (30 points)
The first outline of The Ascent of Man was written in July 1969 and the last foot of film was shot in December 1972. An undertaking as large as this, though wonderfully exhilarating, is not entered lightly. It demands an unflagging intellectual and physical vigour, a total immersion, which I had to be sure that I could sustain with pleasure; for instance, I had to put off researches that I had already begun; and I ought to explain what moved me to do so.
There has been a deep change in the temper of science in the last 20 years: the focus of attention has shifted from the physical to the life sciences. As a result, science is drawn more and more to the study of individuality. But the interested spectator is hardly aware yet how far reaching the effect is in changing the image of man that science moulds. As a mathematician trained in physics, I too would have been unaware, had not a series of lucky chances taken me into the life sciences in middle age. I owe a debt for the good fortune that carried me into two seminal fields of science in one lifetime; and though I do not know to whom the debt is due, I conceived The Ascent of Man in gratitude to repay it.
The invitation to me from the British Broadcasting Corporation was to present the development of science in a series of television programmes to match those of Lord Clark on Civilisation. Television is an admirable medium for exposition in several ways: powerful and immediate to the eye, able to take the spectator bodily into the places and processes that are described, and conversational enough to make him conscious that what he witnesses are not events but the actions of people. The last of these merits is to my mind the most cogent, and it weighed most with me in agreeing to cast a personal biography of ideas in the form. of television essays. The point is that knowledge in general and science in particular does not consist of abstract but of man-made ideas, all the way from its beginnings to its modem and idiosyncratic models. Therefore the underlying concepts that unlock nature must be shown to arise early and in the simplest cultures of man from his basic and specific faculties. And the development of science which joins them in more and more complex conjunctions must be seen to be equally human: discoveries are made by men, not merely by minds, so that they are alive and charged with individuality. If television is not used to make these thoughts concrete, it is wasted.
